VMware
VMware is the market leader in virtualization technology solutions. VMware virtualization inserts a thin layer of software directly on the computer hardware or on a host operating system. This software contains a virtual machine monitor or “hypervisor” that allocates hardware resources dynamically and transparently. VMware's enterprise software, VMware ESX Server, is compatible with all platforms and hardware, and runs directly on server hardware without requiring an additional underlying operating system.
Virtualization allows multiple virtual machines (VMs) to run on a single physical machine, sharing the resources of that single computer across multiple environments. But multiple VMs on the same server compete for the same storage resources – which can result in reduced performance.
Dataram’s XcelaSAN is the industry's first intelligent, block-level Fibre Channel storage optimization appliance that provides high-speed access to frequently accessed data via dynamic caching and resource allocation for maximum application performance.
Shared Storage Requirements
Challenge: Multiple VMs on the same physical server compete for the same storage resources, generating far more disk I/O and throughput than can ordinarily be handled.
XcelaSAN Benefit: By implementing Dataram’s XcelaSAN optimization solution, organizations can avoid the need to upgrade servers while significantly increasing transaction capacity with XcelaSAN as high-speed cache to handle the I/O demand from aggregated VMs.
Storage Bottlenecks in the SAN
Challenge: A company’s remote and local users may experience poor application response times from their virtual desktops due to bottlenecks in the back-end storage and the need to interrupt applications when making storage-related changes.
XcelaSAN Benefit: XcelaSAN can maximize storage performance, support significantly more users and provide better response times.
Budgetary Concerns
Challenge: Cost may prevent companies from upgrading the SAN (storage area network) to meet the demands of VM environments due to cost.
XcelaSAN Benefit: XcelaSAN enables companies to fully utilize currently available storage and add more VMs per server, thereby postponing the need for a forklift upgrade.
